Frequently Asked Questions - RE100P PCE Instruments
How do I install the RE100P controller?
Mount the controller into a panel cutout of 45x45 mm, secure with the provided clips. Connect power and sensor according to the wiring diagram in the manual. Ensure the power supply is off during installation.
What sensor types are supported?
The RE100P supports thermocouple types K, J, T, E, N, R, S, B and PT100 RTD. The input type is configured via the front panel or internal DIP switches.
How do I perform auto-tuning?
Press and hold the SET key for 3 seconds to enter the configuration menu. Navigate to the ATU parameter and set it to YES. The controller will perform a self-tuning cycle to optimize PID parameters.
The display shows an error code like 'E1' or 'HHO'. What does it mean?
'E1' typically indicates a sensor fault (broken or short circuit). 'HHO' means high temperature alarm. Check sensor connections and ensure the measured temperature is within the range.
Can I connect the controller to a computer?
Yes, if your model has the optional RS485 communication port. You can then connect to a PC via a USB-to-RS485 converter and use Modbus protocol for data logging and remote control.
How do I set the temperature setpoint?
Press the SET key briefly. The setpoint (SV) display will start flashing. Use the UP/DOWN keys to adjust the value and press SET again to confirm.
What is the recommended calibration interval?
Calibration is recommended once a year to maintain accuracy. You can adjust the sensor offset using the PVO parameter in the configuration menu.
The output relay is not switching. What should I check?
Verify the relay wiring and ensure the load does not exceed the rated current (3A at 250VAC). Check the output configuration parameter (OUTC) is set correctly. Also test the relay with a multimeter.
Can I use the controller in a humid environment?
The front panel is rated IP65, which protects against dust and water jets. However, the rear terminals are not protected. Use a suitable enclosure if the environment is damp.
How do I perform a factory reset?
Power off the controller. Press and hold the UP and DOWN keys simultaneously while reapplying power. The display will show 'INIT' then reset to default settings.
